Restaurant question (parenting related)

We are putting together a party for my in-laws 40th anniversary. We are looking for a nice restaurant, reasonably priced, with something that could distract the kids if need be. My nephew is autistic and will need a break from the crowd and/or a distraction. My SIL found a place in Roslyn with a pond, but it seems very over priced to me and I'd like to offer up some other options. It will only be in the range of 25-35 people and we are looking for a brunch/lunch. It doesn't even have to be a private room type thing.

TIA
